An odor filtration media having a chemical reagent which removes odor causing fluid contaminants from a fluid stream through the use of granular or shaped media have a chemical composition including permanganate is provided. A method of producing the odor absorbing media having a chemical reagent is also provided and comprises the steps of mixing H2O, KMnO4, and at least one salt adding ions or ionic compounds selected from the group consisting of Na+, Li+, K+, NH4+, Cl−, SO42−, BO32−, CO32−, PO43−, NO3− and combinations thereof, or from the group consisting of Na+, Li+, K+, NH4+, Mg2+, Ca2+, Cl−, BO32−, NO3− and combinations thereof, forming an impregnating solution. The impregnating solution is heated and combined with a support material to form a coherent mass.
